Excellent, thanks! I'll just require the people using the plugin to use
Wireshark 1.2.3 or later. Out of curiosity, though, why not include pretty
much all functions in epan in the epan/libwireshark.def file? Or even
generate it automatically from header files?

Meanwhile, for those curious, using the plugin with an unmodified install
fails, complaining about being unable to find the symbol.
